Shimano CS-HG80 SLX 9-Speed MTB Cassette

If you tend to be hard on cassettes, check out Shimano's CS-HG80 SLX 9-speed mountain bike cassette. The HG80 has a combination of shot-chrome and shot nickel-plated steel cogs that can take a pounding and keep on going. The three largest cogs are mounted on an alloy carrier to reduce weight. Shimano's legendary HyperGlide shift ramps feature computer-designed tooth profiles to improve shifting precision and speed.
